"We weren't able to give some of the other characters that we love – Hodgins (TJ Thyne) and Cam (Tamara Taylor) – more extensive arcs [this year]," exec Stephen Nathan revealed in a recent conference call. "We will be doing that if we get picked up. [Plus] more Booth (David Boreanaz) family stuff."

The current run of Bones will be comprised of 13 episodes, with four 'bonus' episodes - to air after the season finale - still unscheduled.

"[Those four episodes are] more stylised than we normally would do," Nathan explained. "We were able to tackle stories that we might not normally have tackled."
